fllo'alljwhom it may concern:

gfBe it known that I, BENTON BOYD, a citizen of the United States,residing at Uniontown,in the county of Fayette and State ofPennsylvania, have invented a new and use ful Lorry, of which thefollowing is a specification.

The invention relates to improvements in lorries.

Heretofore the amount of coal delivered to a lorry for charging a cokeoven has been measured with the eye, and it has been found by experiencethat the charges, when measured in this manner, vary from five tofifteen bushels even with an experienced person, who is always necessaryin the present construction of lorries.

The object of the present invention is to provide a lorry having ameasurin device, adapted to accurately measure a c arge of coal, andthereby do away with the uncertainty of the present'system of fillinglorries.

A further object of the invention is to provide a measuring device ofthis character capable of adjustment for varying the capacity of thelorry and the consequent size of the charge, and adapted to enable themeasuring device to be readily set for a forty-eight hour or seventy-twohour charge.

With these and other objects in view, theinvention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto a pended; it being understood that various 0 anges in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings ;Figure 1 is an elevation of the body of a lorryprovided with a measuring device, constructed in accordance with thisinvention. Fig. 2 is a plan view of the same. Fi 3 is a central verticalsectional view, t e adjustable measuring device being shown raised infull lines and lowered in dotted lines. Fig. 4 is a detail perspectiveview of a portion of the lorry and the measuring device, illustratingthe adjustable means for suspending the latter within the former. Fig. 5is a detail perspective view of one of the metallic straps of theadjustable measuring device.

Like numerals of reference designate corresponding parts: in all thefigures of the drawings.

The measuring device 1 is in the form of an inverted funnel-shaped cap,and is suspended within the body 2 of a lorry by adjustable means forenabling the measuring device to be raised and lowered to vary thecapacity of the lorry and the size of the char e of coal. The body ofthe lorry, whic may be of any preferred construction, is hopper-shaped,and is provided at the upper portion of it with vertical walls 3 intowhich upper portion the adjustable measuring device telescopes. The body2 of the lorry is shown rectangular in the accompanying drawings,and theadjustable measuring device, which tapers upwardly, corresponds in shapeto the lorry and while it may be constructed of any suitable material,it preferably consists of wooden bars 4 and connecting metallic straps5, which rovide a relatively light construction, which is easily handledin adjusting the measuring device. The bars 4 are spaced apart to exposethe coal as it rises within'the cap, so phat the operator may see whenthe lorry is The measuring device, which has inclined sides, is providedwith a central opening, and

it has an upwardly rojecting extension or neck 6, into which tiie coalis fed for filling the lorry. As the lorry is filled to the top of theneck, it will be ap arent that it will not require the services 0 askilled operator to fill the lorries, so that each lorry Wlll besupplield with a charge of the same amount of coa The coal is generallydelivered to the coke ovens in forty-eight hour charges, seventytwo hourcharges being sup lied to the ovens to run the same over Sun ay. Inorder to enable the lorry to be adjusted for either of these amounts ofcoal, the measuring device is adjustably supported by means of o positeWindlass shafts 7, journaled in suitab e bearings 8 and 9 of the lorry,and connected with the measuring device by means of chains 10, arrangedin pairs and secured at their lower ends to vertical arms 11, consistingof extensions of the metallic straps, which are secured exteriorly tothe wooden bars of the adjustable measuring device. The arms 11 extendupwardly from the opposite lower edges of the measuring device, and arelocated contiguous to the opposite walls of the lorry, when themeasuring device is lowered within the means of eyes 12, or othersuitable fastening means. The arms 11 form guides for steadying themeasuring device, and they are adapted to project above the Windlassshaft 7 when the measuring device is raised. The" upperends oi thechains are attached to and wound around the Windlass shafts, which areprovided with ratchet wheels 13, located adj acent' to the: bearings- 8and engages by F pawl's- 14, pivotally mounted on the said bearings 9and located above the wind-lass shafts. Eachwindlass shaithasits end 15'adjacent to the pawl and ratchet mechanism squared-to receive a crank16, .or other suit able means for" rotating the shaft, for raising andlowering the measuring device. By means of the-windlassshaf-ts theposition of the measuring. device may be quickly changed.-

- Having thus fully described my invention, what I claim as new anddesire to secure by Letters Patent, is:-

1. A lorry open at the top and provided with an adjustable cap extendingover the top of the body of the lorry and having an opening, andadjustable means connected to" the cap and mounted on the body of thelorryfor raising. and lowering the cap to vary the capacity of thelorry.

2.. A lorry openat the top and provided with an adjustable caprnountedon and forming a closure for the open top of the lorry and adapted tovary the ca acity of the same, and means for raisingan "lowering the capincluding chains connected to the cap atthe outer sides thereofio-rsuspending the cap Within the body of the lorry.

3 A lorry open at the top and provided with an adjustable cap mounted onand forming a closure for theopen top ofthelorry and adapted tovary' theca aeity of thesame, said cap being composed 0 "bars spaced apart toexpose the contents to view.

4. A lorry open at the top and provided with an adjustable capmountedover the top of the body of the lorry and adapted to vary the capacityof the same, means for raising and lowering the cap including chainsconnected to the cap, and guide bars for guiding the cap in its verticalmovement.

5. The combination with a lorry, of a measuringdevice consisting of acap having an opening for the passage of the material, wind ass shaftsmounted on the lorry, and flexible connections extending from thewindlass shafts to the measuring device and adapted to be wound. aroundand unwound from the 'EOIHIGITOT raising and lowering the latter;

6 The combination with, a lorry, oi a measuring device consisting oiatapered cap provided with arms extending u wardly from the bottom of thecap, and adjusting means having flexible connections for sue ending themeasuring devicewithin the orry, said flexible connections being attached to the arms.

7 L The combination with a lorry having vertical walls at itsupperp'ortion, of EIHGQJSL uring. device consisting of a tapering capprovided with arms extending upwardly from the lower edges of the cap andarranged con:- tigu'ou's to the opposite vertical walls of the lorry,and adjusting means having: flexible meanssecured to the said armsnearthe lower ends thereof.

8% The combination with a 'lorry having vertical wallsat its upperportion, oia measuring device consisting or an upwardly ta-" peredcaphaving a central opening and pro vided thereat with are'du eedexteirsi on'or neck, arms extending upwardly from the lower edges of thecap, Windlass shafts mounted on the lorry, and'iiexible conned tionsextending from the Windlass shafts to the arms and secured to the sameat the lowerportions thereof.

In testimony, that I claim the foregoing. as I my'own, I have heretoaffixed my signature in the presence of two witnesses.
